COMPARE DEFINITIONS or ADDITION AND SUB
TRACTION.
Flsh's %. t5) Addition is the process OF

Brooks (p. gay Addition Is theprocess OF
finding the sum OF two or more numbers.

which contains as many units as the num-
bers added"
Fish q. 1919 Insurance is security
against loss
Brooks %. $50 Insurance Is contract
OF indemnity for loss or damage within
given time"
The foregoing are some examples OF
faulty and iuadequate attempts at deflni-
tions BY Fish compared With good and auf-

Der must contain all the prime factors oil
that number"
Fish's,. Up. y, says: "3 and 8 - are like
numbers" without explaining the difference

Fish's treatment of fundamental rules IL
meagre by comparison and not as satisfac'

We fall to find sufficient treatment O.
Compound Fractions In Fish's.
Flsh's (p. 221, |. 20,) reads; when stoo
is at par 1t is quoted at 1907" Queries,
What VIII he do with par 2O,dollar shares y
VIII not 50-dollar shares when at par b'
quoted at so, and not at 100 Ought h
not to state: When stock Is at par 1t !

Fish's (p. 19D treatment OF Duties o
Customs Is Inadequate because he gives oil
his problems In U. B. money, wherea
goods are manifested to our country In tn
money Of the country from which they ar
imported. See Brooks (p. BID
XvIT. In Fish's roots are used before mul
tlples. This Is wrong because II puts anal
ysis before synthesls. A root is factor.
multiple is dividend. Build up betor
you tear down.
| In Fish's "factors" used on p. 80, line
and explained on p. 20: Fractions are use,
on p. so and explained on p. 80.
In Fish's Roman notation Is placed o
p. $40 at one-sixth before the close and Avs
sixths after the beginning of the booi
Hence pupil Of Fish does not learn /
read the numbers OF the chapters OF b
I Bible until after he has completed Cub
/ Root and nearly the whole of his arithmetic
, This applies to Fish's Arithmetic NumbC
J Two. He gives Roman notation at the b
